Patient Positioning Procedure

The importance of patient positioning and posture cannot be overemphasized. Carefully follow positioning instructions.

At minimum, three images of the patient's head, neck and thyroid region are required: the frontal view, right oblique view, and left oblique view:

The Frontal View Position and Posture
  1. The image view (palette) should be in 'grayscale.' If not already, set to Grayscale from the Camera Control Menu Bar by selecting 'View,' then 'Palette,' then 'Grayscale.'
  2. Position patient directly facing camera, with toes aligned to a line on the floor.
  1. The patient should be 3- to 4-feet from the camera.
  2. Patient should maintain good posture, and relax with arms by the side.
It is important that patient not touch the face, neck or the upper part of the breastbone throughout the capturing of all images for the examination.
  1. Instruct patient to tilt head back about 30° so both the upper breastbone and the forehead are fully revealed.
  2. Press here to quick focus, and then adjust the camera so the the head and upper breastbone are centered in the image.
Camera Focusing

Camera Focusing is important. Autofocus should be supplemented with fine focusing, as necessary.

  1. Use auto-focus by pressing here:  to automatically focus the camera.
  2. If fine-focusing is not necessary, press 'Continue,' below. If fine-focusing is necessary, press here:  .
  3. Click the 'Focus' button on the Camera Controller to launch the focus control box.
  4. Check to ensure patient's hair is pulled back so all areas of the face including the forehead and auricular regions are uncovered.
  1. Using short single clicks, click the + and - buttons in the Focus Control Box to fine tune image focus, if necessary. Focusing should be adjusted so the entire image is in focus.
  2. When finished focusing, click the 'x' to close the focus control box.
Recording the Frontal View Image
  1. Confirm the patient is in position for the Frontal View
  2. Patient should maintain good posture, with arms by the side.
  1. Instruct patient to tip (angle) head backward about 30°, so that both the forehead and the thyroid region are fully exposed on the screen image.
  2. Press to record the image.
  1. Instruct patient to breathe normally, maintain position, and relax without touching the face, neck or upper breastbone area.
  2. Confirm in the Files window that the new file was created and properly named, e.g. Patient-000001.img.
  1. Click and drag the recorded image file from the Files window to the Camera Control Software window. Assure that the image is properly focused, and clearly displayed.
  2. If the image is judged satisfactory, click 'Continue.' If not, click the 'Retake' button and when the live image reappears, delete the image file (in the File window) and then retake the image.
Capturing the Right Oblique View Image
  1. From the Frontal Position, instruct patient to shift weight to the right foot, and pivoting over the left heel, rotate the left foot counterclockwise 90° so it remains in line with the inside heel of the right foot.

It is very important that after positioning, the patient does not shift weight from the weight-bearing leg to the relaxed leg.

  1. Instruct patient to look straight ahead, with the head level. Slightly rotate the upper torso to fine adjust the rotational position so the right side of the face and neck are completely visible.
  1. Adjust the camera so the head and upper breastbone are centered in the image, as shown.
  2. Assure image is focused. To refocus:   
  3. Press to record the image.
  4. Confirm in the Files window that the new file was created. If not, press 'Record' again.
  5. Instruct patient to maintain position, and relax without touching the face, neck or upper breastbone area.
  6. Click and drag the recorded image file from the Files window to the Camera Control Software window. Assure that the image is properly focused, and clearly displayed.
  7. If the image is satisfactory, click 'Continue.' If not, click the 'Retake' button and when the live image reappears delete the image file in the Files Window and then retake the image.
Capturing the Left Oblique View Image
  1. From the Frontal Position, instruct patient to shift weight to the left foot, and pivoting over the right heel, rotate the right foot clockwise 90° so it remains in line with the inside heel of the right foot.

It is very important that after positioning, the patient does not shift weight from the weight-bearing leg to the relaxed leg.

  1. Instruct patient to look straight ahead, with the head level. Slightly rotate the upper torso to fine adjust the rotational position so the left side of the face and neck are completely visible.

  6. Click and drag the recorded image file from the Files window to the Camera Control Software window. Assure that the image is properly focused, and clearly displayed.
  7. If the image is satisfactory, click 'Continue.' If not, click the 'Retake' button and when the live image reappears delete the image file in the Files Window and then retake the image.
